Head seen from above with the sides moderately extended behind 

 the eyes and but slightly convergent; posterior margin straight across; 

 a sharp carina extending from the buccal orifice to the postero-lateral 

 angles which are moderately prominent, but not acute. Surface of 

 head uniformly, closely, and coarsely, but shallowly reticulate-punc- 

 tate. Antennal grooves margined above by a strong carina. Superior 

 portion of clypeus elevated, flat, hirsute; its apex rounded above; 

 its sides diverging into an oblique, somewhat overhanging ridge 

 which disappears toward the sides of the clypeus; below this the 

 clypeus strongly sloping and depressed, impunctate. Mandibles 

 without an external tooth. Second segment of flagellum a little longer 

 than broad, a little shorter than the third. Dorsum sculptured like 

 the head; the anterior margin of the pronotum rather straight, the 

 humerai angles prominent, ending in an oblique carina below. Te- 

 gulae with few, scattered, setigerous punctures. Surface of scutellum 

 forming a flattened plate, reticulo-punctate ; its sides curved and 

 ending behind in two short, pointed lobes; its posterior margin sinuate, 

 with a short, médian dépression, but raised above the surface of the 

 postscutellum. Sides of the propodeum strongly produced at the angles 

 into a compressed lobe. Upper surface of propodeum with coarse, 

 deep meshes; the basai ones enlarged. Sides of propodeum less coar- 

 sely reticulate. Mesopleurae without a distinct médian fossa; only 

 a weak tubercle beneath the tegulae; an oblique ridge in front of the 

 middle coxae. First abdominal segment greatly widened at its apex; 

 as seen from the side with distinct anterior and dorsal surfaces; its 

 sternite with a strong, erect, acute tooth. Second tergite coarsely 

 punctured, but sparsely and obsoletely so on the disk. Posterior por- 

 tion of the second sternite with a very prominent, médian tooth, 

 sloping in front and truncate behind. Last sternite with a strong, 

 médian, longitudinal tubercle at base. Last tergite striato-punctate; 

 a shallow, depressed area before its apex which is somewhat truncate.
